No. It's because immigrants (and keep in mind that I have no personal immigrancy issues, I am a portuguese who knows damned well how it is like to be an emigrant) do not exactly "conform" to the vision of a secular democracy with human rights meaning that women shouldn't be degraded, etc., and constitute "islands" of muslimhood right inside secular countries.
The immigrant problem, we've had this problem in the West before.
First it was the Catholics, then the Irish, then the Chinese...children of immigrants do become part of society.
Problem is, if you incentivate their own ghetization (?), like, say, creating a different set of laws just for muslims, create religious schools where they get the usual "they say the world is 4.5 billion years old and you are obliged to answer this in the tests but we know better" ridiculous ****fest, and all and all confine the new generations to a whole muslim experience, we are not creating a tolerant, "multicultural", diverse society. We are fragmenting it to pieces and shattering societies.
Private Christian schools exist that do the same thing. You just explained the entire problem behind fundamentalist Christianity in America.
The way you solve this problem is expose that group to secular ideas that counter the backwards beliefs of a Young Earth. The way the Republicans like to do it with Muslims though, is to deride them all as backwards extremists who can't contribute to society, and make no effort to integrate them peacefully.
And don't you think labeling an entire group as savage or disruptive does much for merging that group into society? If anything, it
forces that group to isolate themselves and defend themselves against what they view as a hostile society.
In an ironic way, these religious groups are doing to themselves what some tiranies did to other religious groups in the past: confine themselves.
Tyrannical measures, like, say, racially profiling Muslims and assuming that every Muslim is in favor of enforcing Sharia law on the rest of their countrymen.
What a cop out. People are always savage. And people will act differently according to their beliefs and practices. Religion is one of said beliefs and practices and is very important.
Alright, so tell me, who's more prone to extremism, a poor unemployed young man from Riyadh, or an accounting major from Dearborn?
Demagoguery is a major factor in fomenting extremism among religious groups. For the most part, that doesn't exist in a significant way among American Muslims. If it does exist, it exists as a defensive mechanism against society's persecution of Muslims. It's a self-fulfilling prophecy: the more you isolate a group of people, the more likely they are to turn to extreme measures to defend themselves.
Besides, if you have a stable and comfortable lifestyle, and you don't feel like you're being singled-out for who you are, you're less likely to feel resentment against the people doing it.
